A knockout mouse is a genetically engineered mouse in which researchers have inactivated, or knocked out, an existing gene by replacing it or disrupting it with an artificial piece of DNA.
Problem 9. You are making a knockout of the huntingtin gene in mice and decide to use a mutation in the FGF5 gene to track the contribution of ES cells to the germline. Mice homozygous wildtype (FF) or heterozygous for the FGF5 gene (Ff) have normal fur, but mice homozygous for the FGF5 mutation are very furry (ff).n an ES cell homozygous for the Amendment21 gene, you knock out a single allele of Amendment21 and introduce the resulting cells into a host blastocyst that is homozygous for the Ammendment18 allele. The blastocyst is a transgenic that causes all of its cells to express the red fluorescent protein, RFP.
